Re: Generator Noise
TQUIN45- I appreciate all of the information and comments provided by the members on generator noise. I also have been RV'ing for 7 years. I do understand the liquid cooling on the generator is quieter because of the liquid blanket around the cylinders and head assembly. I also agree that 2 or more cylinders will be quieter since the displacement is smaller in each cylinder and the impulses are separated. I do understand that mounting the generator in the RV may reduce or increase depending on how it is done. At the Winnebago factory they did remove and remount the generator this summer because the dealer installed it wrong. Remounting did help. But, the numbers I am measuring now are after they "fixed" it. Yes, we were within the proper time to run the generator- just after 8 AM and we only use for 15 minutes for the microwave and coffee. We also are sensitive to the noise and thye quiet offered at the campgrounds. What seemed to be missed in my original comments was the Cummins/Onan specification is 68 dBA at 10 feet under 1/2 load!!!! They are doing 78 dBA at 10 feet at 1/2 load. At the rear of the RV it is over 80dBA! I am willing to consider all suggestions but I have done a lot of work on this for the past 5 months. Yes, I did buy and used 2 inch diameter silicon tubing to get the exhaust 9 feet from the RV out the rear but that is not permanent. I also paid over $6000 for a diesel generator rated at 68 dbA . I am planning on replacing the generator with a quiet Honda or Yamaha gas. Again I appreciate all the comments but my goal was for other people to understand the problems with the View, Winnebago,and Cummins. Please keep in mind Cummins may still resolve the problem- they are at least looking at it. Winnebago generally is a good company and usually strives to solve issues. But in my case and some other people they are not responding.1.4KViews0likes0CommentsGenerator Noise
Generator Noise In the past several months I have had to take interest in Generator noise. Back in Aug my wife and I traveled from Mass. to the West coast and did a bunch of National parks. We were asked to shut down our generator because it was too noisy. Our generator is a Cummins Onan RV QD 3200 Diesel. It's output is 3200 watts. Winnebago uses these in their VIEW model. The Cummins noise specification is the noise will be less than 68 dBA at 10 ft and 1/2 load. I have measured (with sound power meter) the noise at 78 dBA which is 10X louder than spec. I spoke to other RV Views owners and theirs are also very noisy. At this point Winnebago will do nothing to help but Cummins has shown interest in helping. The other issue for people to be aware of the location of the generator exhaust- just behind the rear wheel directly under the awning and below the rear bedroom window. Being under the awning goes against all of Winnebago's safety notes- again they will not help by changing the location possibly out the rear of the coach. If anyone has any questions please ask. Note- Honda and Yamaha generators are usually below 58 dBA noise- worth noting if possibly going to purchase one. In my previous RV- a Winnebago Vectra our 8000 watt diesel generator was much quiter than the QD 3200 watt. At 10 ft you could barely hear it. From my experience up to this point be careful if you buy a Winnebago View with a Cummins Diesel generator. The big issue is Winnebago will not step up to the plate and try to resolve the problems of noise and location from the generator.14KViews0likes25CommentsGenerator Noise
